近年來出現了一種採用基於客戶生命周期值的加權rfm （表示客戶生命周期的三個指標變量）技術的推薦方法，這一技術的核心思想就是採用這三個客戶屬性變量的加權和的方法來對客戶進行聚類，其中為變量加權是考慮到不同變量對顧客產生的不同重要程度的影響。對符合某一生命周期類型的客戶按照商品挖掘關聯技術進行商品推薦。這種推薦方法的弊端在於當客戶的交易數據不足以形成規律化的量值時，推薦可能會出現偏差。The results indicate that the design is successful. wt8820 settles the problems of existing wbt and caters to the users, it also adds the diversity of wbt. in a ward, wt8820 is a well performance terminal machine
